Description
Technical field
The present invention relates to a kind of laparoscopic surgery puncture outfits, are a kind of laparoscope instruments, are suitable for laparoscope
It checks and establishes service aisle use in surgical procedure.
Background technique
With the development of medicine and the raising of people's health consciousness, laparoscopic surgery is small with its wound, restores fast, postoperative pain
The advantages such as pain is light, the hospital stays is short play an increasingly important role in Minimally Invasive Surgery, thus with laparoscope be advocate it is micro-
The clinical application of invasive procedures is also more and more extensive.
The principle of laparoscopic surgery is that carbon dioxide gas is used to make artificial pneumoperitoneum as observation and operating space；Use puncture outfit
The duck eye that several 0.5~1.0cm are punctured on stomach wall establishes abdominal cavity and extraneous channel；It is had and is taken the photograph by puncture outfit insertion
Video recording system, light source and other surgical instruments will be transmitted on display the case where abdominal cavity by CCD camera, doctor
It observes and is operated in real time by the image on screen.
Common puncture outfit by puncture cannula, seal assembly, puncture bar assembly and air intake assembly and form, air intake assembly with wear
It pierces casing to be connected, seal assembly is installed on puncture cannula, be plugged on puncture cannula in use, puncturing bar assembly and passing through seal assembly
It is interior.For the leakage for avoiding carbon dioxide gas, seal assembly reaches sealing effect using multi-stage sealed silica gel part composition.But
It is surgical instrument when passing in and out puncture channel, the resistance from seal assembly can be frequently suffered from, doctor is caused to need with bigger
Power operates, and over time doctor's hand can be uncomfortable.Correspondingly, seal assembly can be led when for a long time by bigger pulling force
Mutagens shape cannot be restored, in time so as to cause seal failure.
Patent CN204049782 discloses a kind of seal assembly of puncture outfit, and the seal assembly is by sealing lower cover, sealing
Circle, sealing upper cover, sealing lower cover, elastic sealing element, supporting element and sealing upper press cover composition, wherein elastic sealing element is by 5
Identical notched cone composition, every angle of circumference is 225 °, the overlapping angle of every two pieces is 153 °.In the puncture outfit
Multi-stage sealed component because the piece number is excessive, overlapping area is excessive, to puncture needle and other surgical instruments in conversion process repeatedly
Resistance is brought, so that doctor's operation has some setbacks.
In order to solve resistance problem, there is seal assembly to change structure, also there is additive on seal assembly or puncture cannula
Reduce resistance, but these methods are all different degrees of that there is respective deficiencies.
Patent CN207152631 discloses a kind of small resistance sealing ring, and the sealing ring is by the sealing that more than two valves constitutes
Enclose and be divided into more than two support chips composition on each valve of sealing ring.The magnetic to attract each other is arranged on each valve of the sealing ring
Item or magnetic powder, and support chip is made of plastics or metal one kind hard material.In clinical application, puncturing lever is usually by metal material
Composition can have some setbacks when passing through the sealing ring with magnetic stripe or magnetic powder, and the support chip being made of hard material also can be to puncturing lever
Puncture bring resistance.
Patent CN105943131 discloses a kind of puncture outfit of self-lubricating, and the puncture outfit is by puncture cannula, core bar, casing
Seat, conversion cap, core rod seat, lubrication assembly composition.The lubrication assembly is by micropore bag and the lubricant grease group in micropore bag
Pass through service aisle at, surgical instrument or core bar, micropore bag, which is squeezed, can squeeze out lubricant grease, lubricant grease and surgical instrument or
Core bar contact reaches lubricant effect.In clinical application, puncturing core bar front end is mostly sharpened configuration, micro- when it passes through micropore bag
Hole bag is easy to be punctured rather than squeeze, and greasing substance can largely discharge, and inflow human body causes damages.
Patent CN202665587 discloses a kind of self-lubricating puncture outfit, which is made of puncturing lever and sheath, in sheath
There are the medical elastic porous material and medical lubricant that can be absorbed, store and discharge medical lubricant.Puncturing lever and lubrication assembly
When contact, the sharpened configuration of puncturing lever leading portion can destroy medical elastic porous material, especially more in puncturing lever or surgical instrument
It is destroyed after secondary puncture more seriously, the porous material after destruction is easy to produce clast, and it is harmful that clast, which enters human body,.In addition,
It selects Medical silicone oil to will lead to seal assembly made of silica gel material as lubricant to mix with silicone oil, destroys the sealing of puncture outfit
Performance.
As can be seen that there is no very good solution resistance problems for the above-mentioned published patent, thus need to continue to improve.
